Lot of good advice here on how to make good decisions and strategic choices to make a better life for yourself.
But, I'm here to give a different perspective. I'm going to retire soon and I've never had a sensible career plan in my life that lasted. I've bounced from opportunity to opportunity like a piece of driftwood in the surf. I've made my career choices based on what seemed like a good idea at the time. I've been a company director, I've been broke and (fortunately only technically) homeless and everywhere in between. I've had stressful jobs and easy-going jobs. All of which is to say that plans are good but sometimes winging it can work out too.
The other thing I will say is that while I've worked some shit jobs and some great jobs, I've always done a good job regardless. I've treated bosses, colleagues, and subordinates fairly and honestly. So those opportunities I mentioned a paragraph ago, they came because people I've worked with were happy to work with me again.
